The microblogging startup is testing out several new features with select businesses and organizations, a part of Twitter’s effort to charge companies for advanced tweeting capabilities that are off-limits to individual users like you and me.

Those new features that Twitter calls the Twitter Business Center are currently limited to a private group of select business account holders until the company feels confident enough to roll them out to everyone. According to an exclusive Mashable report, the biggest feature by far is the ability for businesses to accept tweets from any of their followers, which will especially come in handy in customer care scenarios:

The ability to accept direct messages from any of their followers, regardless of whether they follow that person or not, is huge for businesses that perform customer service via Twitter: they can get feedback and deal with private customer issues without having to follow the person back first.

Another cool addition is the ability to register as a verified business or organization, which is a must if your brand is to be taken seriously. Previously, Verified Twitter Accounts have been limited only to individual accounts.

According to the report, Twitter revealed no pricing details for the Twitter Business Center, yet another indication that the microblogging startup is still figuring out how to monetize the service and finally begin making some money.

That being said, the Twitter Business Center is certainly a step in the right direction. Businesses of all sizes are now extensively using Twitter as a very effective channel for communication with both the customers and the media, a tell-tale sign that Twitter is here to stay. If the company can build more services like the Twitter Business Center that sport advanced features which businesses need, the money will pour in and Twitter will thrive. Otherwise, the startup could be in big trouble if it spends VC money before setting up its own revenue streams that need to support their operations.
